Bonus Symmetries of N=4 Super-Yang-Mills Correlation Functions via AdS Duality
arXiv:hep-th/9811047 · doi:10.1016/S0550-3213(99)00242-4
Abstract
General conjectures about the SL(2,Z) modular transformation properties of N=4 super-Yang-Mills correlation functions are presented. It is shown how these modular transformation properties arise from the conjectured duality with IIB string theory on AdS_5 x S^5. We discuss in detail a prediction of the AdS duality: that N=4 field theory, in an appropriate limit, must exhibit bonus symmetries, corresponding to the enhanced symmetries of IIB string theory in its supergravity limit.
